Question

What is the pH of sodium chloride?

Answer 1

Hint: We need to know that the pH scale is used to identify the acidity or alkalinity for any aqueous solution. Acidic solutions (solutions with higher concentrations of H+ ions) are measured to have lower pH values than basic or alkaline solutions and neutral salts have pH of seven.

Complete answer:
We have to know that sodium chloride is a salt having a chemical formula\[NaCl\]. When sodium ions interact with chlorine ions electrostatic attraction occurs due to which salt sodium chloride is formed. There are many ways for the production of sodium chloride out of which very basic is an acid base reaction. In which sodium hydroxide that works as a base and hydrochloric acid which works as an acid combine together to form sodium chloride that is a salt, this reaction can also be termed as neutralization reaction. Now we know that acid has a pH value lower than seven while a base has a pH value greater than seven,
\[NaOH + HCl \to NaCl + {H_2}O\]
In the above reaction that is the formation of sodium chloride, it is a neutral product thus we can say that sodium chloride has a pH value of seven i.e. the neutral range. A salt that is derived from the reaction of a strong acid with a strong base forms a solution that has a pH of $7$ .

Note:
We have to know that when a strong base and strong acid reacts together they do not hydrolyze instead they form a neutral product. In the case of sodium chloride neutralization reaction; Sodium hydroxide is a strong base while hydrochloric acid is a strong acid.
